id: CVE-2023-6634

info:
  name: LearnPress < 4.2.5.8 - Remote Code Execution
  author: iamnoooob,rootxharsh,pdresearch
  severity: high
  description: |
    The LearnPress plugin for WordPress is vulnerable to Command Injection in all versions up to, and including, 4.2.5.7 via the get_content function. This is due to the plugin making use of the call_user_func function with user input. This makes it possible for unauthenticated attackers to execute any public function with one parameter, which could result in remote code execution.
  remediation: Fixed in 4.2.5.8
